IPC: F16B21/04
Filed: 1962-05-03
Abstract: 1,009,354. Clamps. ILLINOIS TOOL WORKS Inc. May 3, 1962 [May 5, 1961], No. 17037/62. Heading E2B. [Also in Division F2] A fastener, e.g. of nylon and for joining apertured workpieces or securing a channelled moulding strip to a panel 24a, Fig. 8, has a head integral with a shank 26, Fig. 4 (26a, 26d in other figures) having an opening at one end and an element 54 (54a, 54b, 54d, 54e, 54f) inside the shank (or insertable into it through the opening) so that when rotated it expands the shank laterally, Fig. 8. In Fig. 4, which does not show the head, the expander element 54 is a tongue extending from a closed end of the shank 26 and when twisted to separate walls 42, 44 it may be wedged at its free end in grooves 68,74 between ribs in the shank. A notched tool, Fig. 1(not shown), is used to twist the tongue. In Figs. 5 and 8, the element 54a is elliptical in section like the shank bore and has a slot 82 to receive a tool 76a. The element, as indicated in Fig. 5, may be joined to the head by a breakable section before being forced into the shank and turned so that the major axes of the element and bore sections are perpendicular one to another, Fig. 8. There may be a bead 86 to prevent the element being pushed out by the tool 76a. To resist retrogression there may also be ratchet teeth like those 90 on a cam surface 186, Fig. 9, of an expander element 54b of a modification in which the shank bore 78b has cam surfaces complementary to the cams 186. The element 54b may initially be joined to the head. A similar fastener with cam surfaces, Figs. 14, 15 (not shown), has, at the toolreceiving end of the expander element, cutaway portions at the edge to form two shoulder faces in a diametral plane, the top of each face being connected to the bottom of the other by a ramp in the manner of a dog-clutch to engage a corresponding tool. In Fig. 16, the shank 26d contains two U-shaped sockets 100, 102 to receive lugs 96, 98 of a flat expander element 54d which is narrow enough for insertion in the shank but long enough so that, when pivoted about the lugs in the sockets to lie transversely in the shank, it distends two opposite portions of the shank 26d to hold the fastener in an aperture. A central aperture in the element may be defined by axially-inclined resilient prongs 106e, Fig. 19, or by a helically-deflected margin 106f, Fig. 20, to receive respectively a pin or a screw.

Title: Electric-pulse generator suitable for use in pulse communication systems
IPC: H03K3/16
Filed: 1944-09-13
Abstract: 594,659. Pulse generating and modulating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Sept. 13, 1944, No. 17541. Convention date, April 10, 1943. [Class 40 (v)] In a pulse generator a delay line is associated with a thermionic valve, the flow of current in the valve initiating a potential wave which is propagated down the line and reflected to produce at the transmitting end an increased potential to terminate the flow of current in the valve. Coupled coils 11, 12 in the anode and grid circuits of valve 1 ensure rapid increase of current, the line L being connected between the cathode and earth and terminated by a valve 2 which acts as a variable resistance. As the line L discharges through valve 2 the cathode potential falls until valve 1 conducts, the anode current in coil 12 inducing a voltage in coil 11 which is applied to the grid of valve 1 to cause a rapid increase in the anode current. The cathode of valve 1 is driven positive rapidly, a positive wave being sent down line L to the valve 2 which presents a resistance greater than the characteristic impedance of the line L so that the wave is reflected to increase the potential on the cathode of valve 1, thereby cutting off the anode current, the line L discharging through valve 2 to complete a cycle. The coupling coil 13 feeds the pulse produced by the flow of anode current through coil 12, to a pulse amplifier 10 feeding a magnetron 16. To minimize the effects of variations in the supply voltage, the screen grid of valve 2 is fed through a resistance-condenser combination (i, 8 having the same time constant as the combination comprising the condenser C1 and the effective resistance of the screen grid circuit. The screen potential of valve 1 may be stabilized by a neon tube. For pulse modulation purposes, an audioamplifier 3 varies the grid potential of valve 2, the line L being discharged at a greater or lesser rate to vary the interval between pulses.

Filed: 1937-06-25
Abstract: 479,658. Multiplex wireless signalling. STANDARD TELEPHONES & CABLES, Ltd. June 25, 1937, No. 17723. Convention date, July 18, 1936. [Class 40 (v)] In a multi-channel system in which the signals of each channel are caused to modulate a subsidiary carrier, the subsidiary carrier is suppressed when the transmission of signals over the channel stops. The pentode amplifier modulator AM of one channel, Fig. 1, has its control grid G connected to the oscillator O. Speech signals amplified in the valve F are impressed upon the suppressor grid GS; the output of AM is used to modulate the main carrier in the transmitter T. The valves AM in all the channels have a common anode feed PA and common resistance L. Normally, a prohibitive bias, -100V., is applied to grid G through the armature of relay RI. When the channel is in use, speech from transformer 4 is rectified in detector LR, causing the relay to change over and put a lower bias, -10V., on grid G, thus allowing the valve AM to operate. In modifications, Figs. 2, 3 (not shown), the relay LR changes the polarization of the suppressor grid GS. To prevent clipping of the speech due to inertia of the relay, a speechretarding device, such as a recording system, may be inserted after the amplifier F. The potentials for polarization may be derived from an impedance in the circuit of valve LR, Figs. 4, 5 (not shown). Provision may be made at the receiving end to block a channel until its respective carrier wave is received. The selective amplifier A, Fig. 8, is fed from the common amplifier AMC, and feeds the detector unit B comprising the double-diodetriode DDT, which supplies AVC potentials over the circuit RAG, low-frequency potentials over condenser C4, and a D.C. potential over filter C2R3 to the grid of the triode portion, which causes the removal of the blocking voltage from the succeeding amplifier PAM.

Title: Improvements in or relating to switching apparatus for selecting and operating sets of electrical contacts
IPC: H01H67/26
Filed: 1919-07-17
Abstract: 141,005. Belay Automatic Telephone Co., (Assignees of Betulander, G. A.). April 2, 1919, [Convention date]. Automatic exchange systems. - Relates to switching-apparatus, particularly for automatic exchange telephone systems, in which groups of spring contacts for connecting incoming and outgoing lines are arranged in parallel rows and can be selectively operated electro-magnetically by selecting and operating members arranged perpendicularly to each other, of which the former selects, say, the vertical row containing the wanted set of contacts, while the latter operates that set of contacts which is in the horizontal row corresponding to the operating-member in question. According to the invention, the number of selecting-members is reduced by making each member common to two or more sets of contacts. In the arrangement shown in Figs. 1, 2, and 4, one hundred sets of contacts 1 are arranged in ten horizontal rows on shelves 2, the contact sets of the top and bottom rows only being shown in Fig. 1. The contacts of each horizontal row are actuated by a member 8 integral with the armature 9 of a magnet 10. Each set of contacts 1 has an operating-spring 25 having a stepped end 26 which is arranged above an aperture 27, Fig. 4, in the member 8. Thus, if the arms 23, 24, Fig. 4, attached to the vertical selecting-members 12 controlled by magnets 17, are in the normal full-line position shown in Fig. 4, the movement of member 8 by magnet 10 is without effect on the contacts 1. Each of the five vertical members 12 has two armatures 19, 20 for two magnets 17, so that, by energizing one or other of the magnets 17, the vertical member 12 can be rocked in either direction to bring the arm 23 or 24 across one or other of the apertures 27 in the member 8 as shown in dotted lines in Fig. 4. Thus, if one of the magnets 17 is operated and then one of the magnets 10, the arm 23 or 24 forms an operative connexion between the member 8 and the stepped end of the spring 25 of a set of contacts 1 determined by which pair of magnets 10, 17 is energized. The arms 23. 24 are made resilient so that they may remain gripped between the parts 8, 26 when the member 12 returns to its normal position. In a mcdification, a single arm carried by the member 12 moves a spring secured to the shelf 2 over the aperture 27. In a further modification, the vertical members 12 are arranged between the sets of contacts 1 and near their rear ends so as to facilitate the adjustment of the contacts. The members 12 have a pair of spring arms 24, Fig. 9, carrying balls 36, which form an operative connexion between the member 8 and the contact springs 1. In a third modification, a single arm carried by the member 12 moves a spring secured to the switching member 8 so as to form an operative connexion between the member 8 and one or other of the sets of contacts associated with the member 12.
